【相关描述】 To palliate, extenuate, cloak. These words, as here compared, are used in a figurative sense in reference to our treatment of wrong action. We cloak in order to conceal completely. We extenuate a crime when we endeavor to show that it is less than has been supposed; we palliate a crime when we endeavor to cover or conceal its enormity, at least in part. This naturally leads us to soften some of its features, and thus palliate approaches extenuate until they have become nearly or quite identical .
